Abstract
A motor cooling fan unit comprises a tubular cover capable of surrounding a motor and a fan provided to blow air toward the interior of the cover. The motor cooling fan unit is configured to cause air blown from the fan to pass through a flow path between the motor and the cover. The cover comprises an exhaust part provided at a downstream area of the flow path. The exhaust part comprises: an open part for making the flow path communicate with the outside; and an exhaust adjusting member provided for the open part and movable between a shield position at which the exhaust adjusting member covers the open part and an open position at which the exhaust adjusting member opens the open part. The amount of movement of the exhaust adjusting member is adjusted to allow adjustment of the amount of the air in the flow path to be exhausted through the open part and a direction of the exhaust, or adjustment of the amount of the air to be exhausted or a direction of the exhaust.
